iPhone
Sit tall, without thinking about it.
Plumb is a calm, private posture-awareness companion. It learns the comfortable "tall" you set for yourself, gently notices when your head drifts forward, and nudges you to ease back — at your desk, or hands-free through your AirPods.
A prompt to notice, not a verdict. Plumb learns your neutral, not a textbook ideal — and the fastest way to lose your trust would be to overclaim, so it stays plain-spoken about what it can and can't do.
TWO WAYS TO USE IT
Hands-free with AirPods — the everyday mode. Plumb reads your head position from compatible AirPods or Beats, so your phone can stay pocketed or locked. A soft tone cues you the moment you drift past your own threshold, and goes quiet the instant you ease back.
Camera at your desk — the screen-attended alternative. The front TrueDepth camera reads your head position at desk distance — and your shoulders when they're in view. Frames are processed in the moment and immediately discarded — never previewed, saved, or uploaded.
It can't see your lower back, and we won't pretend otherwise.
CALM BY DESIGN
• A gentle nudge — a soft tone, a tap, or both. It gets slightly more insistent on a long slump, and stops the moment you ease back.
• Breathing and small shifts inside your neutral zone never count.
• A "held tall" timer tracks your time in a comfortable position.
• A stylised living figure reflects how you're holding your head — no camera image or video is ever stored or shown back.
• Insights answers one honest question: am I improving? A clear average, an honest change once there's enough history, and quiet days left as blank space, never guessed.
• Learn — six short, evidence-anchored reads on why noticing your posture matters, each with its limits stated plainly.
YOUR POSTURE NEVER LEAVES YOUR PHONE
• Everything is analysed on your device. There are no Plumb servers and no backend — there's nothing to send.
• No account, ever. No sign-up, no email, no login.
• No ads, no trackers, no analytics, no third-party SDKs.
• iCloud sync is off by default and opt-in; it goes only to your own private iCloud.
• Apple Health is write-only — Plumb can log a Mindful Minutes session and never reads your health data.
SIMPLE, TIME-METERED PRICING
Time is the only free meter — no feature walls.
Free, forever: one check-in a day across both modes, up to five minutes, with the full nudge experience, the pain log, your two-week Insights window, and the whole Learn library.

• Plumb+ Lifetime now costs less — same everything, smaller number
• Dozens of small refinements across the app
Posture, gently.
